Estimation and ModelingSemi-parameter regressionPrecision analysisThe measuring model based on Bi-satellite as well as optical and radar measure was presented; and then the sparse parameter estimation model and the corresponding estimation algorithm and calculation step for exterior ballistic trajectory based...
Hence, this general prior formulation is helpful in analyzing the properties of different modeling approaches and their connections. We derive the estimation procedures with these priors using variational inference for fully Bayesian estimation. In addition, we discuss the differences between the proposed ...
In this study, sparse modeling is introduced for the estimation of propagation patterns in intracardiac atrial fibrillation (AF) signals. The estimation is based on the partial directed coherence function, derived from fitting a multivariate autoregressive model to the observed signal using least-squares...
Thus some limitations of the ZUPT approach we propose the novel method based on transient artifact reduction algorithm (TARA) to mitigate these errors by noise estimation. TARA is the novel approach to estimate the low-frequency components in the signals by applying the concept of sparse ...

In many scientific studies, it becomes increasingly important to delineate the causal pathways through a large number of mediators, such as genetic and brain mediators. Structural equation modeling (SEM) is a popular technique to estimate the pathway effects, commonly expressed as products of coefficie...

In particular, we derive a thresholding operator based onthe KEP function, and prove its mathematical properties and asymptoticproperties in sparsity modeling. Moreover, we show that a coordinate descentalgorithm is especially appropriate for the KEP function. Additionally, wediscuss the relationship of...
